LIFEBOOK B2620 (850mhz, 30gb, 256m)

These machines are available on ebay for under 200 bucks, and they are nice
little touchscreen machines that run linux great, if you can figure it out. 
These are my notes, as it has been lots of trial and error, and google is not
so helpful on some of these issues.

INSTALLING LINUX

As far as I can tell, the machine will _only_ boot from HD or USB external
floppy, and nothing else.

If there is no OS, you will probably need a USB floppy, and a floppy installer.

If Windows is installed, you can install grub, and if linux is already
installed, and you have grub, then this page has all the info to bootstrap a
network install from the HD:

    http://marc.herbert.free.fr/linux/win2linstall.html

Basically, you get 'linux' and 'initrd.gz' for your distro, put them in /boot,
and add an option to /boot/grub/menu.lst to boot that. reboot and select the 
new entry, and it kicks off a network install.

TOUCHSCREEN

It took me a year to get the touchscreen to work right. Linux recognizes it out
of the box, but it is completely unusably uncalibrated. After much trial and 
error, finally, I got it working with the following:

Get the evtouch driver:

    aptitude install xserver-xorg-input-evtouch

Find out what device the touchscreen is:

    cat /proc/bus/input/devices

Look for something like:

    ...
    I: Bus=0011 Vendor=0002 Product=0009 Version=0003
    N: Name="LBPS/2 Fujitsu Lifebook TouchScreen"
    P: Phys=isa0060/serio1/input0
    S: Sysfs=/class/input/input3
    U: Uniq=
    H: Handlers=mouse2 event3 
    B: EV=b
    B: KEY=400 0 70000 0 0 0 0 0 0 0 0
    B: ABS=3
    ...

The Handlers line tells you the device. Next you need to find your calibration
values. Get the calibrator file from:

    http://www.nextabyte.com/support/touchscreen/

(also mirrored here) and run:
    
    sudo ./calibrator /dev/input/event3

or whatever event you found in the previous step. This will launch a
calibration screen, and upon exit, gives you the magic numbers for xorg.conf. 
According to the docs, the calibrator is supposed to actually edit your 
xorg.conf - for me, it did not, and I had to add stuff by hand. This page
helped with that:

Here is a diff of my xorg.conf and the original. There is a new InputDevice
section, with the magic numbers from the calibrator in there. And the last
line gets added to the ServerLayout section.

    < EndSection

You can also take a look at my current xorg.conf in this directory. The magic numbers are not always perfect, and some trial and error with tweaking them a bit can certainly help.
